each row can be specified as a percentage or fixed height.  Row widths can also be fixed, percentage or auto.
This class is intended to be extended or created via the layout:'ux.row' <a href="output/Ext.Container.html#Ext.Container-layout" ext:member="layout" ext:cls="Ext.Container">Ext.Container.layout</a> config,
and should generally not need to be created directly via the new keyword.</p>
<p>RowLayout does not have any direct config options (other than inherited ones), but it does support a
specific config property of <b><tt>rowHeight</tt></b> that can be included in the config of any panel added to it.  The
layout will use the rowHeight (if present) or height of each panel during layout to determine how to size each panel.
If height or rowHeight is not specified for a given panel, its height will default to the panel's height (or auto).</p>
<p>The height property is always evaluated as pixels, and must be a number greater than or equal to 1.
The rowHeight property is always evaluated as a percentage, and must be a decimal value greater than 0 and
less than 1 (e.g., .25).</p>
<p>The basic rules for specifying row heights are pretty simple.  The logic makes two passes through the
set of contained panels.  During the first layout pass, all panels that either have a fixed height or none
specified (auto) are skipped, but their heights are subtracted from the overall container height.  During the second
pass, all panels with rowHeights are assigned pixel heights in proportion to their percentages based on
the total <b>remaining</b> container height.  In other words, percentage height panels are designed to fill the space
left over by all the fixed-height and/or auto-height panels.  Because of this, while you can specify any number of rows
with different percentages, the rowHeights must always add up to 1 (or 100%) when added together, otherwise your
layout may not render as expected.  Example usage:</p>
<pre><code><i>// All rows are percentages -- they must add up to 1</i>
<b>var</b> p = <b>new</b> Ext.Panel({
    title: <em>'Row Layout - Percentage Only'</em>,
    layout:<em>'ux.row'</em>,
    items: [{
        title: <em>'Row 1'</em>,
        rowHeight: .25
    },{
        title: <em>'Row 2'</em>,
        rowHeight: .6
    },{
        title: <em>'Row 3'</em>,
        rowHeight: .15
    }]
});

<i>// Mix of height and rowHeight -- all rowHeight values must add</i>
<i>// up to 1. The first row will take up exactly 120px, and the last two</i>
<i>// rows will fill the remaining container height.</i>
<b>var</b> p = <b>new</b> Ext.Panel({
    title: <em>'Row Layout - Mixed'</em>,
    layout:<em>'ux.row'</em>,
    items: [{
        title: <em>'Row 1'</em>,
        height: 120,
        <i>// standard panel widths are still supported too:</i>
        width: <em>'50%'</em> <i>// or 200</i>
    },{
        title: <em>'Row 2'</em>,
        rowHeight: .8,
        width: 300
    },{
        title: <em>'Row 3'</em>,
        rowHeight: .2
    }]
});</code></pre></div><div class="hr"></div><a id="Ext.ux.layout.RowLayout-props"></a><h2>Public Properties</h2><div class="no-members">This class has no public properties.</div><a id="Ext.ux.layout.RowLayout-methods"></a><h2>Public Methods</h2><div class="no-members">This class has no public methods.</div><a id="Ext.ux.layout.RowLayout-events"></a><h2>Public Events</h2><div class="no-members">This class has no public events.</div></div>
